Defects in Semiconductors 2020

Defects play key roles in a range of materials. Applications include silicon chips, energy-efficient solar cells, and light-emitting diodes, as well as emerging areas such as quantum computing and 2D materials. Advances in thin-film growth, microscopy, spectroscopy, and theory are leading to an unprecedented glimpse into atomic-level properties of point and line defects. This Collection on Defects in Semiconductors provides a valuable forum where researchers studying the fundamentals of defects in semiconductors can share their most recent and novel findings.
